Default 6080 se cathode follower

Hello everybody,
I'm going to build a power amp output 3.5w/channel from cathode with one 6080.
I need help here before I go...
Any ideas ?
Many thanks in advance.
Singh

The trick, as always with CF output stages, will be getting a very linear, very high voltage capability driver stage. This will not be a trivial undertaking!

Its not as hard as it sounds to get a good linear driver for the 6080. These tubes are at their happiest when run hard and low. I have had great success running them at 100V and 100mA, which gives a drive of about 60V Peak to Peak - which is well in the capabilities of most driver stages.
